FractWall (Fractal Wallpaper generator) is a program for generating BIG fractal images (currently only Mandelbrot)

The program is written in Java and can be built using ant.
Execute the program with java -jar FractWall.jar [options]
where options might be:

-width <int> The width in pixels of the generated image
-height <int> The height in pixels of the generated image
-xaos <filename>.xpf A save-file from the xaos fractal generator (Only the
xmin,ymin,xsize and ysize are set from this file.) You
need to set width and height before you use this switch.
-xmin <double> The minimal real part of the area to calculate
-ymin <double> The minimal imaginary part of the area to calculate
-xsize <double> The real part range of the area to calculate
-ysize <double> The imaginary part range of the area to calculate
-maxiter <int> Maximum number of iterations per pixel
-ncolors (2|16|256) Number of colors in the palette 2 means black and white.
16 and 256 gives a grayscale going from black to white
and all the way back to black again: 16 colors example:
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,14,13,12,11,10,9,...
(black = 0) only if maxiter is reached.
-output <filename> The output file. Since the program currently only
supports gif-files, it should end with '.gif'
-q Quiet, do not show calculated height so far (0...height)
-type mandel Type of fractal, Mandelbrot - 'mandel' is the only
supported for now
